Title: Formation of film
Inventor: KATO TAKASHI
IPC: H01L21/768
Filed: 1985-02-16
Abstract: PURPOSE:To bury the sharply stepped portion with a film in a short period of time by depositing a film with isotropic chemical vapor growth method on a substrate to which a bias voltage is applied. CONSTITUTION:A thick silicon dioxide film 3 is deposited also at the sharp side wall of 90 deg. in a recessed portion 2. Thereby, the recessed portion 2 is quickly buried because the silicon dioxide film 3 is deposited from both the side wall and botton directions. After the recessed portion 2 is buried completely, an angle theta2 of inclined surface at the remaining stepped portion is small. Therefore, the surface of silicon dioxide film 3 becomes very smooth. When the deposition rate by the CVD method is increased and is matched to the peak of etching rate by sputter etching, the angle theta becomes about 45 deg. and such condition is the most optimum state for burying the recessed portion 2.

Title: Production of light-transmission glass material
Inventor: AOKI MIKIO
IPC: C03B8/00
Filed: 1987-02-09
Abstract: PURPOSE:To easily obtain a light-transmission glass material having a definite concentration gradient, by diffusing a dopant into a porous glass, developing a concentration distribution of the dopant, fixing the distribution and cooling and drying the obtained material. CONSTITUTION:A dopant is sufficiently diffused into a porous glass material and the dopant is eluted by immersing the glass in a solvent such as a mixture of alcohol and water to develop a concentration distribution of the dopant. The dopant concentration in the obtained glass has a gradient from the surface toward the inner part. The obtained composition is cooled, dried and sintered to obtain the objective glass having refractive index distribution. Since the cooling and drying of the porous glass material is carried out after developing a concentration distribution, the process is effective in preventing the relaxation of the concentration distribution caused by the dissolution of once fixed dopant into a solvent. Accordingly, the dopant concentration in the obtained porous material has accurate parabolic distribution. A transparent glass material having a refractive index forming a parabolic distribution can be produced by heating and sintering the porous material.

IPC: G11B7/126
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To automatically adjust recording power by detecting the resolution of a regenerative waveform of a signal recorded on an optical disk. SOLUTION: Initial adjustment of the recording power of an optical head 14 is processed by an optical system control circuit 17 in an inspection process after completing an assembly process in a production line. After recording a prescribed signal in a prescribed area of the optical disk 12 by the optical head 14 in changing stepwise the recording power, the prescribed signal is reproduced in changing slice levels in turn for the purpose of detecting an envelope of the regenerative waveform, and the resolution of the regenerative waveform is detected from the slice levels corresponding to the detection of a signal pattern having a prescribed period from the regenerative waveform, and then the recording power of the optical head 14 is automatically adjusted accordingly.  Consequently, no time is taken in the inspection process after assemblage, and adjusting work of the recording power is not required, and hence inspection work is carried out in a short time.
